新的react-native ios应用程序没有构建？

Question

以下是有关我的环境和构建失败日志的详细信息.任何面临类似问题或知道克服此问题的步骤的人请指出相关步骤或文档.

• Xcode:7.2.1
• 节点:v5.9.0
• npm:3.7.3
• react-native-cli:0.1.10
• 反应原生:0.22.2

运行"sudo react-native run-ios"给我留下了下面的日志.

日志:

Answer 1

别跑:

sudo react-native run-ios

你应该跑:

react-native run-ios

您的root帐户没有正确配置模拟器来运行iOS,因此您在日志中看到"没有设备被启动"错误!

Answer 2

我在OS X El Capitan v10.11.4上有类似的问题

node --version v6.0.0
npm --v 3.8.8
react-native-cli: 0.2.0
react-native: 0.24.1
watchman --v 4.4.0
xcode 7.3

我在react-native github上创建了一个问题.

我能够解决我的问题:

对我来说,端口8081正在使用中:

lsof -n -i4TCP:8081

node 7601 arun 23u IPv6 0xc6b249599e5f1169 0t0 TCP *:sunproxyadmin (LISTEN)

所以我按照React Native Troubleshooting中的说明操作并杀死了pid

kill -9 7601

并react-native run-ios再次运行命令,一切都按预期工作(在节点6上也是如此).
